Smart Contract-based Protocol for Efficient Project Scheduling in Industrial Internet

Multi-robot services are widely used to improve the efficiency of industry Internet applications, especially in smart factories. Under the situation that the tasks are becoming more and more intensive, how can smart factories use limited robot resources to complete tasks more efficiently? In order to solve this problem, we transform it into a resource-constrained multiproject scheduling problem, and consider using a combinatorial auction method to get the solution. In order to ensure the security of the system and solve the transaction cost of the robot system, we adopt Blockchain technology and smart contracts to organize the work of the robots. We finally conducted performance analysis of our proposed method, and the results show that smart contracts and combined auction algorithms are safe and effective.
